CLAMP FOR MOLD-BOARDS.

SPECIFICATION forming part of Letters Patent .No. 233,868, dated November 2, 1880.

Application filed Septembcr15, 1880. (No model.)

To all whom it may concern Be it known that I, WVILLIAM MONARY, of Bryan, in the county of Williams and State of Ohio, have invented certain new and useful Improvements in Devices for Glam pin g Mold- Boards and Landsides for Flows; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of my in vention as applied for use, or holding a moldboard. Fig. 2 is a longitudinal section thereof. Fig. 3 is a detailed perspective view of the same, and Fig. 4. is a cross-section thereof.

This invention relates to improvements in clamps for holding mold-boards or landsides of plows or other plates of steel, its object being to permit of the convenient manipulation of the plate ofsteel, mold-board, orlanrlside while being tempered and it consists of a V-shaped grooved head, with curved grooved arms, having handles, substantially as hereinafter more fully set forth.

In the accompanying drawings, A indicates a V-shaped head, slightly concaved on each side of its apex toward the ends of its divergent portions. This is to adapt it to conform to the shape of the forward end of a moldboard or landside of a plow, while it is apparent it is capable of receiving the end of any other shaped piece or plate of steel or metal to that extent to hold it temporarily.

The head A is provided with a groove, (1, extending along its inner surface to receive the end of the plate, mold-board, or landside.

B B are two arms, articulated to the extremities of the head A, also concaved longitudinally to conform to the curvature of the longitudinal edges or surfaces of the mold-board or laudside, and having grooves b b on their inner surfaces to receive and hold the same or other plate of steel or metal. To these arms are provided handles 0 O for conveniently operating the clamp. This clamp, it is obvious, will receive and permit of the holding of a mold-board or landside of a plow, or by a simple change of form hold a plain or right-arr gled or rectangular plate of metal or steel, which is especially convenient in dipping the mold-board, landside, or plate, for tempering the same in any of the usual or approved forms of tempering baths or solution.

A collar, D, is slipped upon the arms B to clamp or confine the inclosed plate, mold-hoard, or landside between the arms and in the head, which can be readily slipped. on and off said arms as occasion may require.

it will be further noticed that, with the edges of the mold-board, landside, or plate inserted into the grooved arms and heath-and with the collar slipped firmly upon the same, the metal will be prevented from warping when plunged into the tempering-bath.

Having thus fully described my invention, I claim and desire to secure by Letters Patent- 1. In a clamp, the combination, with the head A, of the articulated arms B, having handles O, with grooves extending along the inner surfaces of said head and arms, substantially as and for the purpose set forth.

2. In a clamp, the combination, with the head A, of the articulated arms B, having handles O, both the head and arms having grooves, and the collar D, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of August, 1880.

WVILLIAM MONARY.
